To all whom it may concern:

, .Be it known thatI, CHARLES R; KARoPnw of the city ofBrantfo-riinthepcounty of" I Brant, Province of Ontario Canada; a subject of theKing ofGreat vented certain new and"useful-Improve-.

- mentsin Snubbing Attachments for Vehicles, of which the-following is aspecification.

This invention relates to improvements in simple, 'which may be attachedto thegvehicle with a minimum of trouble; and which may be constructedat areasonable cost.

I attain my object bym'eans 'of the constructions hereinafter describedand illus trated in the accompanying drawings in which i Fig. 1 is aside elevation; partly in sec- 7 tion, showing mydevice attached to avehicle;

Fig. 2 a-plan view, partly in section; Fig.3 a side elevation of thebox, springs and lever, the cover being removed; and

Fig; 4: a view showinga modified form of clip'for use when the device isapplied to the rear axle of a vehicle.

Fig. 5 is a detail of a modified construction of the spindle and lever.

In the drawings like numerals of refer ence indicate corresponding partsin the difierent'figures.

.1 is part of the frame of the chassis. of a motor vehicle and 2 thefront axle both of which are ofordinary construction. 3 is a box orcasing,'which is secured to -the member'l .by bolts or screws 4 passingthrough the member'l. Centrally of the box 3 is journalled the spindle 5carrying the rock v arm 6. Each end of the rock arm connectedthereto aspring 7, .the other end "of each spring being connected to a pin orother projection 8 on the bottom of the box 3, or thescrews or bOltS tmight pass clear through-the bottom of the box and the ends of thesprings 7 might be connected to these projecting ends.

A. lever 9 is secured to" the spindle 5 which extends through the sideof the box 3; The

lever and spindle may, however, be made integral if desired. To theouter end of this lever is secured one end of a coil spring I 10. Theother end of this spring has a clip 11 secured thereto which clip issecured to Applicaticnlfiled May. 14,

:the axle of the vehicle. This clip will be formed as: shown in Figs. 1and 2 when used in connection with Ithefront axle of the vehicle, and:formed-asshow'n in Fig. 4 when used for attachment with the rearaxle.

The operationof the device is as follows. v I ThespringsTandthespring-1O willnormallybe in tension. When thewheels pass Iover an. irregularity in the surface of the road, the axler2 and-member1 tend to first approach'onei another, andnthen to spring. Y

apart. As the axle 2 and member .1 separate,-the' spring 10, whichnormally tends tolimit the separation; .is drawn on, which draws downthe levier9; which at 'thesame time move's'the spindle 5 and rocks thearm 6,the springs {7,- however; tending-to prevent or limit thisseparating movement. As

1 the axes of the springs 7 approach the spindle 5, their effect on thelever decreases of thisspecification;

What I claim as my invention is: i

1. In a snubbing attachment for vehicles,

the combinationwith the frame and axle of the vehicle, of a spindlejournalled on the frame of the vehicle; a rock arm secured onsaidspindle; a lever connected at one end to said spindle; meansconnecting the other end of the lever withthe axle of the vehicle; aspring secured to said rock arm, the other end of said spring beingsecured to a stationary part, said spring and said means being adaptedto resist separation of'the frame and axle, saidrock arm and springbeing so positioned and proportioned that the axis of the springapproaches the spin dle as the rock arm is moved through in-- creasedseparationof the frame axle.
